Jiu Zang easy metamorphic tea packaging equipment to extend the shelf life

China is the hometown of tea, and drinking tea has become one of the traditional Chinese food culture. With the continuous improvement of people's living standards and the improvement of the concept of healthy health, tea drinking is increasingly sought after by people. In the market, the variety of tea is constantly enriched, but different teas have a certain shelf life. For example, black tea and Pu'er tea belong to fermented tea. However, the emergence of tea packaging machinery has made tea packaging more diversified, and at the same time extended the shelf life to a certain extent.

According to relevant sources, in general, tea needs to be stored dry, otherwise the wet environment is easily contaminated by harmful microorganisms such as mold, white mildew spots on the surface, and musty smell, which is more obvious when brewing. In addition, the tea leaves are stored for too long, the quality will be greatly reduced, affecting the taste. If you drink mildewed tea, it will cause discomfort.

With the improvement of processing technology and tea packaging equipment, the shelf life of bulk black tea is generally 18 months. The shelf life of black tea packed in canned bags, canned or wrapped in aluminum foil by food packaging equipment can be up to 24 months. In life, most of us are tea bags packed in bags, cans and aluminum foil.

Taking bagged tea as an example, at present, the bag tea packaging machine on the market can be used for automatic packaging of tea, health care products, food and other materials. The machine first puts the material into the inner bag, and then puts the inner bag into the outer bag, so that the inner and outer bags are simultaneously packaged, and the degree of automation is high, and the processes of bag making, metering, filling, sealing, slitting and counting can be automatically completed. At the same time, the package size can be quickly changed according to the packaging process, and the width may be adjusted easily and quickly by the adjustment handle, which not only improves the packaging efficiency, but also ensures the packaging effect of the tea.

The author was informed that the nylon triangle bag tea packaging machine launched by a certain company in Shanghai has made it possible to produce tea bags with outstanding extraction and beautiful appearance through ultrasonic sealing and cutting. At the same time, using Siemens PLC controller from Germany, the performance is stable and the operation is simple and convenient. In addition, according to user requirements, different combinations of sub-assembly forms can be used to expand the weighing range, compatibility is strong, and it is easy to use with other packaging equipment. Unlike bagged tea packaging, canned tea leaves need to be bottled. The author understands that the tea can packaging production line can realize the automatic operation and control functions of the whole process of automatic bottle handling, weighing, filling, capping and sealing after manual bottle feeding and material preparation. At the same time, the adjustment of the bottle shape of each part is realized by the rotation of the handle, and the operation is simple and easy. The tea wrapped in aluminum foil paper needs to be vacuumed, which is used in vacuum packaging equipment. Vacuuming is mainly to create a vacuum in the bag, so that the packaged tea leaves can achieve oxygen, moisture, mildew, insect and pollution prevention, effectively extending the shelf life and freshness period, and facilitating storage and transportation. It is understood that the tea automatic vacuum packaging machine developed by a certain city in Zhuzhou is made of plastic aluminum foil composite film or plastic composite film. It can be vacuum-sealed and packaged for tea, etc., by discharging air and filling with inert gas such as nitrogen. The color, aroma and taste of the tea are stable, and at the same time, the packaging volume is reduced after vacuum packaging, which is convenient for transportation and storage.

It can be seen that compared with loose tea leaves, the application of related packaging equipment, improving packaging efficiency, saving enterprise costs, and extending the shelf life, making tea easy to store and transport, to a certain extent, to ensure the quality of tea.
